The sculptures from the Parthenon in Athens, and copies of them, are controversial objects. Countless organisations across the world display casts of them, often full sets, but the originals are harder to bring together easily.

This cast, on display in a Greek airport, is accompanied by text reading: “The originals of blocks 3, 4, and 5 are exhibited at the Acropolis Museum while the original of block 2 is in the British Museum.” There’s a not-so-subtle nod there in the interpretation about the integrity of the complete frieze, famously split over a few museums.

As tourists end their trip to Athens, there’s a reminder about the international spread of these objects. Some suggest there’s a requirement for museums to work internationally to bring tell the story of the Parthenon as a whole. Others argue it would be simpler to reunite the collection in one place.

One thing’s for certain – these objects will continue to spark debate and attract attention for years to come. And the way we interpret these objects is set to change, perhaps subtly, over time.
